Hi,
what is the preferred way to get at another process's environment variables? /proc/$$/environ looks like the most portable way [across all arches Linux runs on], but it cannot easily be mmap'ed because the size is not known. In fact, mmap does not seem to work at all on that file. So I would have to allocate a large buffer (4K is the limit for procfs files AFAICR) to potentially hold big environments, which does not sound really wise either. Or is it the best choice available?
